Corrigendum: Investigating the dynamic responses of Aegilops tauschii Coss. to salinity, drought, and nitrogen stress: a comprehensive study of competitive growth and biochemical and molecular pathways
The detrimental effects of drought have adverse impacts on the crop yield as global climatic changes put unusual pressure on water resources. The challenge of attaining water security is key for the sustainable development of crops. Zinc (Zn2+) is an important nutrient that helps to alleviate drought stress by modulating the growth and yield of crops. Recently, zinc nanoparticles (ZnNPs) have been used as a novel strategy for the fertilization of crops. This study was specifically developed to observe the comparative effects of ZnNPs and conventional zinc sulfate (ZnSO4) at diverse concentration levels (0.01%, 0.05%, and 0.1%) that could effectively decrease the injurious effect of drought stress on turnip plants. In experiments on the golden turnip variety, drought stress caused a significant reduction in all growth and biochemical attributes, and increased antioxidant enzymatic activity. In a comparison with the conventional fertilizer ZnSO4, the foliar application of 0.1% ZnNPs significantly improved plant height, biomass, root/turnip length, turnip diameter, antioxidant defense system, secondary metabolites, and photosynthetic pigments in the leaves under drought stress. Based on the collected results, it is suggested that the foliar application of ZnNPs, instead of ZnSO4, under drought stress is helpful in increasing the growth and yield of turnip plants.
Solidago canadensis is an invasive weed that grows successfully under adverse environmental conditions and shows a high capability to various habits.To evaluate the role of local adaptation in the invasion of S. canadensis into heterogeneous environments, the morphological and physiological traits of S. canadensis plants were studied under salt (control, 100 and 150 mM NaCl), drought stress conditions (control, 75 and 100 g L -1 PEG-6000) and abscisic acid (ABA) (0, 25, and 50 ul L -1 ) application.Salt treatments significantly reduced the plant height, shoot dry weight (SDW), water use efficiency (WUE), intracellular CO 2 , and net photosynthetic rate (NPR) by 8.17, 28.75, 21.65, 20.71 and 35.44%, respectively than control plants.Among salt treatments, maximum reduction was found under 150 mM NaCl followed by 100 mM NaCl and control treatment.Salt treatments demonstrated a nonsignificant effect on leaf fresh and dry weight, root length and stomatal conductance.Similarly, drought stress significantly reduced the leaf fresh weight, leaf dry weight, plant height, stomatal conductance, and NPR with maximum reduction under severe drought condition (100 g L -1 PEG-6000), where the values were 31.01, 30.39,35.09, 49.19 and 46.93% lower respectively than control plants.In this study, ABA application had not significantly influenced the morpho-physiological traits of S. canadensis.Reduced plant height, SDW and NPR under both stresses and reduced WUE and intracellular CO 2 under salt stress suggest some degree of phenotypic plasticity under these stress conditions.
The invasion of non-native plant species presents a significant ecological challenge worldwide, impacting native ecosystems and biodiversity. These invasive plant species significantly affect the native ecosystem. The threat of invasive plant species having harmful effects on the natural ecosystem is a serious concern. Invasive plant species produce secondary metabolites, which not only help in growth and development but are also essential for the spread of these plant species. This review highlights the important functions of secondary metabolites in plant invasion, particularly their effect on allelopathy, defense system, interaction with micro soil biota, and competitive advantages. Secondary metabolites produced by invasive plant species play an important role by affecting allelopathic interactions and herbivory. They sometimes change the soil chemistry to make a viable condition for their proliferation. The secondary metabolites of invasive plant species inhibit the growth of native plant species by changing the resources available to them. Therefore, it is necessary to understand this complicated interaction between secondary metabolites and plant invasion. This review mainly summarizes all the known secondary metabolites of non-native plant species, emphasizing their significance for integrated weed management and research.
